What branch will I be on after doing that?  Detached at that branch?

Did you know that the general way to spell the branch previously you
were on is "@{-1}" and "checkout -" is an ugly special case that is
possible only because "checkout" does not happen to take a "-" as a
valid argument that means something else (like the more usual "read
from standard input")?

Perhaps 

	$ git branch -D @{-1}

would have worked without <BACKSPACE> and everything that follows.
